Polymer modification is a promising approach to improve the joining performance of injection molded direct joining (IMDJ) technology. However, the factors contributing to the improved joining strength of submicron scale surface pattern joints have not been fully elucidated. In this study, we investigated the mechanism for improving the joining performance of polyamide 6 (PA6)/aluminum alloy A5052 joints with Blast + hot water treated metal structure using a flow modifier (OSGOL MF-11). Enhanced mechanical polymer infiltration at the submicron scale was confirmed, and the hydrogen bond generation at the joint interface was characterized. These findings elucidate the reason for the joining performance improvement caused by the flow modifier in the submicron scale.

Superhydrophobic coatings by electrodeposition on Mg–Li alloys: Attempt of armor-like Ni patterns to improve the robustness

Due to the fragility of the layered structure, the mechanical properties of superhydrophobic surfaces, particularly wear resistance, are still too poor, limiting the industrial application of protecting magnesium-lithium (LZ91) alloys from corrosion. As a result, we’re testing screen-printed masks to electroplate armor-like Ni columns. Then, using electrodeposition, compact micro/nanometer-sized papillary structured superhydrophobic surfaces are created on Mg–Li alloys, which exhibit good low viscosity, self-cleaning, chemical stability, and excellent corrosion resistance with a 2 order of magnitude decrease in corrosion current density in both corrosive media. Surprisingly, increasing the deposition time causes the dissolution of Cu anode electrodes and the subsequent formation of Cu compounds on the superhydrophobic coating, resulting in the formation of dense needle-like structures on these papillae. Even after the superhydrophobic structures are worn away, the armor-like Ni col- umns reduce the contact angle’s tendency to decrease. This proposed deposition method provides a simple and fast process for protecting the surface of Mg–Li alloys, and the concept of armored Ni patterns may pave the way for future advances in the robustness and application of superhydrophobic coatings.
